Sheared bolt need help.

I have an 05 Vue with the 2.2 and man. tranny and 125,000 miles. I was having a lot of noise from my timing chain area, so I bought a new chain kit, and tore into the motor. The black plastic chain guide was in about 11de-billion(well it was more like 5 or 6) pieces, and had sheared the bolt which holds it on . If anyone can take a pic, or describe this bolt to me I would appreciate it. Does it have a large shoulder or something? It looks like it does in order to fit the slot. Is there somewhere online I can get one? I have been searching all day and I got nothing. I live about 100 miles from the nearest Saturn dealer, so I can't go ask them. I would also be willing to pay for one if someone has one laying around...... Thank you for your time.
